In an embodiment of the invention as shown in the drawing, the slide fastener 10 has the usual pendant member or operating handle 11 fastened to the pull member or slider 12. The pull member 12 in cross-section is similar to the sliders 23 in cross-section, except that it is provided with an upright central member 50 riveted or otherwise secured at 51 and being slotted to receive the operating handle 11. The fastener strips or stringers E, F, have longitudinal pockets 34, 35 and may comprise two pieces 13 and 14 as shown in Fig. 4 or four pieces 15, 16, 17 and 18 as shown in a modified form illustrated in Fig. 6. In both cases the outer edges may be held together by stitchings 19 and 20. The free edges of these pockets of the tapes or fastener strips may form tubings 21, to provide enlarged or beaded edges or pipings, each of which may enclose a core or filler 22. The stifiening beads may be formed in any other suitable manner. The fastener of the present design makes use of four beaded edges or pipings. Arranged in alinement and associated with the said beaded edges are the pull member 12 and sliders 23.

Sliders 23 constructed of flexible or rigid material, consists of the'central gui e channel 24 which is preferably just wide eno gh to accommodate and slidably engage the two center beaded edges 25 and 26 of the pockets. The two side flanges 27 and 28 which are turned reentrantly to form outer guide channels accommodate and slidably. engage the side edges 29 and 30 of the pockets. The opening of the central guide channel is reversely located with respect to the outer guide channels. The grip on the beaded edges is free enough to permit the sliding of the members 12 and 23 thereon.

At 31 and 32 hook-like projections are provided which clamp the flexible tie cords 33. i The tie cords 33, which are attached to all sliders 23 and pull member 12, pulls the said members into their respective spaced positions shown in Fig.

' 2, and hold the slide members 23 in their properly spaced relations, when the adjacent strips or stringers E, F are brought together into closed position. When the device is in open or released position, the cords 33 fold up within the pockets 34, 35 of the fastener strips, as clearly illustrated in the broken portion of Fig. 3. Any other suit, able means may be employed to link the sliders together.

As shown in Figs. 3 to 5, inclusive, the flat portion 36 of the slide member 23 will show on the reverse side of slide fastener 10. In most cases this reverse side is hidden from view. But in cases, where a complete concealing of all sliding parts is desirable, the modified .form shown in Fig. 6 may be employed. In this form, the free edges 3'7, 38 of side flanges 27,28 of Fig. 5 are lengthened to 37', 38' of Fig. 6, to overlap portions 36 of the slide member, thereby taking the stringers 39, well over the slide members 23'.

When the slide fastener is in complete, open or disengaged position as indicated at Fig. 3, all the sliders 23 are together in alinement at the end A of the device which end is located beyond the desired opening. Assuming that the device is applied to a pocketbook, for example, these sliders will be located on a side thereof as shown at B in Fig. 1.'

When the guide channels of the sliders are arranged as indicated in the drawing, the direction of pull of the stringers is such as to prevent its strips or tapes from separating.- 4

In the embodiment of slider indicated in Figs. 8, 9, the numerals 55, 56, represent the outer guide channels having the respective openings 59, '60 through which the beaded edges 29, 30 are entered for engagement therewith. 57 is the central guide channel having the opening 58 through which the beaded edges 25, 26 are entered for engagement therewith. The central channel 57 is offset with respect to the part 36' connecting the outer channels (36' being the equivalent of 36 in the drawing) so that the part 36' of an adjacent slider will overlap portion 57 as indicated in Fig. 9, when the sliders are bunched together like that shown in Fig. 3.

It is believedfrom the above description that those skilled in the art will have no difliculty in understanding the construction, the method of use and operation of the deviceherein disclosed and a detailed discussion thereof is unnecessary. The invention is of simple and practical construction and is adapted to accomplish among others all of the objects and advantages herein set forth.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features, that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.
